Slide 4
The Four Layers The Earth is composed of four different layers.
The crust is the layer that you live on, and it is the most widely
studied and understood. The mantle is much hotter and has the
ability to flow. The outer core and inner core are even hotter with
pressures so great you would be squeezed into a ball smaller than a
marble if you were able to go to the center of the Earth!
Slide 5
CRUST : Composition: Made of Silicon (Si), Oxygen (O), and
Aluminum (Al) Thickness: The thinnest layer 0-32 KM (0-19.8 miles)
State of Matter: Solid cool rock Temperature: 200 to 400 C (392F to
752F)
Slide 6
Still CRUST: Interesting Facts: The outermost layer of the
earth Two types of crust: oceanic, continental Oceanic (ocean
floor) is thinner continental (mountains) is thicker It is part of
the Lithosphere. Lithosphere: crust and upper mantle
Slide 7
MANTLEMANTLE Composition: Made of Magnesium (Mg), Si and O.
Thickness: The largest layer 2,868 KM (1,800 miles) State of
Matter: Plastic-like - Hot liquid magma Temperature: 870 to 2200 C
(1,598F to 3992 F)
Slide 8
Still MANTLE: Interesting Facts: There are three parts: Upper
mantle, Middle Mantle, and Lower Mantle (80% of Earth) No one has
ever drilled into the mantle. It is part of the Asthenosphere.
Convection currents cause UPLIFT, moving molten rock closer to the
crust/surface. Convection currents Tectonic plates move around on
the mantle.
Slide 9
THE Outer CORE Composition: Made of Iron and Nickle Thickness:
2,300 KM (1,429 miles) State of Matter: Hot molten liquid
Temperature: 2200 to 5000 C (3992 to 9032 F)
Slide 10
THE Outer CORE Interesting Facts: The outer core spins around
the inner core. This motion creates a magnetic center.
Slide 11
THE Inner CORE Composition: Made of Iron and Nickle Thickness:
1,300 KM (808 miles) State of Matter: Solid iron Temperature: 5000
to 6000 C (9032 to 10832 F)
Slide 12
THE Inner CORE Interesting Facts: Is the hottest layer of the
Earth. Is a magnet due to the spin of the outer core.
